Video: Gears of War 2 grenade tags and melees ... through walls?

Here's a video that'll cause even more "give us a darn Gears 2 game patch Epic!" demands, one that shows off a newly found multiplayer game bug that just shouldn't have made it through play testing.

Seemingly, anywhere a wall can be accessed from both sides, players are able to not only melee another player through the wall, but also stick them with a grenade. We're pointing this out because it's actually a BIG and annoying bug rather then a user exploit or glitch. It's in the game and just shouldn't be. Please, "give us a darn Gears 2 patch Epic!"
